Product details
The AT91SAM9R64-CU-999 from Microchip Technology revolutionizes Embedded - Microcontrollers for medical electronics, combining ultra-low noise performance with stringent safety certifications for life-critical applications.The ARM926EJ-S architecture implements dual-core lockstep with cycle-accurate comparison, detecting faults within 10ns to meet IEC 62304 Class C requirements.A 16/32-Bit processing width enables single-cycle execution of complex DSP filters for real-time biosignal processing in patient monitoring equipment.Operating at 240MHz with <10 V supply noise, the microcontroller maintains analog signal integrity for precision ECG front-ends with <0.5 Vp-p input-referred noise.The EBI/EMI, I²C, Memory Card, SPI, SSC, UART/USART, USB interfaces incorporate medical-grade isolation up to 5kVrms, enabling direct connection to patient-connected sensors without external isolation barriers.AC'97, POR, PWM, WDT include medical-specific features like lead-off detection and right-leg drive amplifiers, reducing external component count in diagnostic equipment.With 49 channels supporting <1nA leakage current, the device can interface directly with high-impedance biopotential sensors without buffering.32KB (32K x 8) accommodates FDA-approved algorithm implementations with full traceability and version control for regulatory compliance.The ROM implementation features hardware-enforced read-only regions for critical code segments, preventing unauthorized modifications.72K x 8 of ECC-protected memory prevents silent data corruption in drug delivery systems where single-bit errors could have life-threatening consequences.The 1.65V ~ 3.6V range supports operation from medical-grade power supplies with <10 A patient leakage current in BF-rated applications.Precision A/D 3x10b achieve 20-bit effective resolution through oversampling and chopper stabilization, enabling direct digitization of microvolt-level biosignals.The Internal design maintains <1ppm frequency stability for accurate timing of therapeutic delivery systems where dosing accuracy is critical.Rated for -40°C ~ 85°C (TA), the device operates reliably in sterilization cycles and extreme clinical environments.Surface Mount packaging uses biocompatible molding compounds that outgas <1 g/cm in vacuum environments, suitable for implantable applications.The 144-LFBGA format provides <1pF pin-to-pin capacitance, preventing signal crosstalk in high-density medical imaging front-end electronics.Available in 144-BGA (13x13), the microcontroller is manufactured in ISO 13485-certified facilities with full device history tracking.
